18650 Lithium Battery, 0.96 Inch OLED Display, Wi-Fi, Bluetooth ESP32 Shield Module, ESP-32 ESP8266 CP2102, Development Board Module
Product Description
- Supporting Lua program, easily to develop.
- Supporting three modes: AP, STA, and AP+STA.
- Small volume, easily embeded to other products.
- Strong function with support LWIP protocol, Freertos.
- High performance-price ratio.
When you do some ESP32 projects you must hate to add a power bank to provide the power. This tiny board could solve such problems. A LG 3000mAH 18650 battery could make ESP32 run 17 hours or more.

Stepper motor 28BY J-48 with Driver ULN2003
the ULN2003 stepper motor driver or in English stepper motor, unipolar (4 phases/ 5 wires ) allows you to easily plug the small motor 28BY J-48 5v gràce to the 5 pin male connector and connects easily to an arduino or other through a 4 pin connector for control signals and Gnd (ground/-). The power supply of ULN2003 is between 5 and 12V.
The « LJ12A3-4-Z/BX » is an inductive proximity sensor that detects metal objects within a 4mm range. It operates on a DC 6-36V power supply and has an NPN (Normally Open) digital output, meaning it completes a circuit to the signal line when it detects metal. These sensors are used in industrial automation for non-contact switching, control, and detection
